thanks very much, dana, for that. and kate has some new information about a story. >> a very interested day in this convoluted tale, as heisman trophy runner-up, manti te'o, is trying to explain to the world why he lied about falling in love with woman who doesn't exist. te te'o's extended interview about the scam just aired with katie couric. he was very emotional at tiles, george. >> kate, it was an interesting interview. at first, he insisted that he did not lie about it. then he backed off that a bit and admitted that he did, kind of, sort of. but throughout the interview with katie couric, he insisted that he really believed that his girlfriend was real. that is, until he realized that he had been duped. then he didn't know what to say about it. in his first televised interview since the scandal broke, notre dame star linebacker manti te'o spoke to katie couric about the online girlfriend he'd never met face to face, a woman we now know never existed. >> manti, did you have any involvement in creating this scam?
